Childhood Overweight and Obesity
Obesity is a serious health concern for children and adolescents. Results from the 2007-2008 National Health and Nutrition Examination Survey (NHANES), using measured heights and weights, indicate that an estimated 17 percent of children and adolescents ages 2-19 years are obese. Between 1976-1980 and 1999-2000, the prevalence of obesity increased. Between 1999-2000 and 2007-2008 there was no significant trend in obesity prevalence.
Among pre-school age children 2-5 years of age, obesity increased from 5 to 10.4% between 1976-1980 and 2007-2008 and from 6.5 to 19.6% among 6-11 year olds. Among adolescents aged 12-19, obesity
increased from 5 to 18.1% during the same period.1, 46
Obese children and adolescents are at risk for health problems during their youth and as adults. For example, during their youth, obese children and adolescents are more likely to have risk factors associated with cardiovascular disease (such as high blood pressure, high cholesterol, and Type 2 diabetes) than are other children and adolescents.2
Obese children and adolescents are more likely to become obese as adults.3, 4 For example, one study found that approximately 80% of children who were overweight at aged 10–15 years were obese adults at age 25 years.3 Another study found that 25% of obese adults were overweight as children.5 The latter study also found that if overweight begins before 8 years of age, obesity in adulthood is likely to be more severe.
